HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 356,554, dated January25, 1887.

Application filed November 17, 1886. Serial No. 219,146. (No' model.)

To all whom it may concern:

Beit known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county ofMiddlesex and State of Massachusetts, a citizen of the United States,have invented a new and useful Improvement in Heel-Nailin g Machines, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part of thisspecification, in explaining its nature.

The object of the invention is to provide means for driving into a heelor heel-blank two gangs or groups of nails or fastenings in successiveorder; and it comprises a templet having a double line of holes, orholes through which two lines of nails or fastenings may be driven, anailcarrier having two lines of holes for feeding two lines of nails insuccessive order and transferring them to the templet, a reciprocatingcross-head carrying a block supporting two gangs or groups of awls, andwhen the heel is flush-nailed only a block carrying two gangs or groupsof drivers. When it. is blind-nailed,there will be two groups or gangsof drivers used; but they will be separated from each other and attachedto separate holding-blocks.

The invention also comprises nail-distributing devices having twonail-holders into which two gangs or groups of nails are automaticallyfed, and a supplemental double nailcarrier arranged to receive nailsfrom both holders, and to transfer them in successive order to thenail-carrier.

The invention further relates to various details of organization andconstruction, all of which will hereinafter be described.

In the drawings, Figure l is a view in vertical section of parts of themachine necessary to illustrate my invention. Fig. 2 is a plan View of asupplemental plate having a coin pound or double nail-holder. Fig. 3 isa plan view inverted thereof, showing its guides and cap-plates and thesliding covering-plates for covering the holes of the holders. Fig. 4 isa plan view of the nail-carrier and a part of the nail-carrier plate.Fig. 5 is a view to illustrate two gangs or groups of nails driven as inflush-nailing. Fig. 6 is a plan view of a heel, showing one'line drivenasin blind-nailing and the other as in flush-nailing. Fig. 7 is a planview of the templet and nail-carrier gangs of nails of different sizesto the holes of the carrier represented in Fig. 7. Fig. 9 is a plan viewof the supplemental nail-carrier plate. Fig. 10 isa vertical section ofthe central and upper parts of a heel-nailing machine having thefeatures of myinvention. Fig. 11

is a view of a revolving head having two gangs or groups of awls carriedby one holdingblock, and two gangs or groups of drivers carried by oneholding-block. Fig. 12 is a View of the awl-holding block for two gangsor groups ofawls. Fig. 13 is a view of the driver drivers. Fig. 14 is aview of a revolving head having arms for holding the two groups of awlsand drivers separate. Fig. 15 is a view in plan of a templet-plate,showing the double line of holes.

A is the last or work-support; a, the jack; a, the bed upon which itslides. A is the cross-head. It is reciprocated in any desired way, andit carries a revolving head, A, which has an arm, atcarrying a blockholdingagang or group ofawls, a and another gang or group of awls, a,the arm a which holds a block carrying a gang or group of drivers, a,and a gang or group of drivers, a, and an arm, a holding or carrying abreasting knife, a". hen the revolving head is automatically rotated,instead of arranging the two groups of awls and the two groups ofdriversas described, I provide the revolving head with a separate arm for eachgroup of awls and a separate arm for each group of drivers, (see Fig.14,) and I prefer to use for rotating it automatically substantially themechanism described in the Henderson and Raymond Patent No. 317,647, al-

though I do not limit myself to the especial devices therein described.

B is the templet. It is formed in the end of or supported by thetemplet-plate b, and it may be stationary so far as the horizontalmovement is concerned; or it may be moved horizontally by a cam andsuitable connecting devices, as described in Patent No. 290,109. It hastwo lines of holes-first, the line b, and

holding-block for two gangs or groups ofsecond, the line I). The line bis a complete line, and is the line through which the principalattaching-nails are driven. The line b may or may not be complete, andit may be inside of the line b or outside thereof, according to theposition which it is desired the nails shall have in the heel. (It isshown outside in Figs. 12 and 13.)

G is the nail-carrier. It is formed in or supported by the end of theplate 0, and it has a horizontal movement provided it by meanssubstantially as described in said Patent No. 290,109. Both it and thetemplet-plates are represented as supported by the verticallymovabletable 0, which is like that described in said patent. The said carrierhas two lines ofholesfirst, the line a, which holds theprincipalattaching-nails, and second, the line 0 which holds the supplemental oradditional nails. These holes are covered by the sliding plate 0, andthe holder may be operated so that a single group or gang only of nailsshall be delivered at a ti me to the templet-that is, the cam for movingthe carrier 0 may be so constructed or shaped that it moves it inward todeliver one gang of nails, then backward to receive another, then inwardagain to deliver another gang which are fed into the other holes of thecarrier, and then inward to deliver this second gang, and then backwardagain.

To supply the two sets of holes a c successively and automatically withnails or fastenings,l have arranged a compound distributer, whichcomprises, essentially,a nail-holder, D,

having nail-holding holes dof the same arrangement as the groups I) 0 ofthe templet and nail-carrier, and the nail-holder D, which has its holesd arranged in the same order as the groups 0 If of the nail-carrier andtemplet. These two nailholders D D preferably are arranged closelytogether and over the nail-carrier plate 0, and between them and thenailcarrier plate is a supplemental double nailcarrier plate, E. Thisnail-carrier plate has the nail holder 6, the holes e of which areadapted to register with the holes d of the nail holder D, and thenail-holder e, the holes e of which are arranged to register with theholes (1 of the holder D.

The supplemental double carrier E has a sliding hole-covering plate, e,for the holder 0, and the sliding hole-covering plate 6 for the holder0', and the holding-plate c has the projections e", and the plate 6 theprojections 6 the ofiice of which will hereinafter appear.

The plate E is moved bya cam (not shown) and connecting-lever, e and theplate is given movements in relation to the nail-holders D D and thenail-carrier O, as follows: At the end of a backward movement-of thedirect carrier-plate c the nail-carrier O is brought into a position toreceive nails from the nail holder 0, which is then moved transverselyto it until its holes come in register with the holes a, when a gang orgroup of nails is delivered to the carrier 0. The sliding plate 6 ismoved to uncover the holes by the contact of the projection c with theside of the carrier 0. The carrier 0 is then moved forward, the plate Eremaining stationary, and after the nails have been delivered to thetemplet and driven the carrier is returned to its back position, and theplate E moved by its cam in a reverse direction to bring the holes 6 ofthe holder 0 in register with the holes c of the nail-earrier 0, wherebythe second gang or group of nails is delivered to the carrier, and thecarrier is then moved forward again to feed the second gang or group ofnails to the holes b of the templet. The sliding plate a is moved touncover the holes of the holder 6 by the stop or projection a coming incontact with theside of the nail carrier plate, and both sliding plates6* e are closed automatically to cover the holes by the springs e e, theplate 6* by the spring e", and the plate e by the spring e Thesupplemental carrier-plate E is then returned by its cam to its normalposition un der the holders D D, and the nail-making machine started.

Any suitable nail-making devices may be employed, and in the drawings Ihave repre sented only the receivingblock F of the Towns and RaymondPatent No. 346,137,which is arranged to receive the nails from thenail-making devices; and I would say in this connection that it receivesnails differing in length, so that the group of nails delivered to theholder D shall be long, if desired, and the group delivered to theholder D short. The receiving-block F is moved forward with anintermittent motion, and backward with a continuous movement, and itdelivers its nails in two gangs or groups-first, 'a gang or groupthrough the passages g of the distributer G, which conducts the nailsand guides them to the holder D, and, second, through the passages g ofthe distributer G, which conducts nails to the holder D. Thisdistributer, how

ever, is like in all essential parts that de-' scribed in my Patent No.346,125.

The nail making anddelivering mechanism is not started to deliver thenails to the receiving block until after the supplemental carrierplatehas delivered both loads of nails to the main nail-carrier and returnedto its normal position.

The supplemental nail-carrier plate may have the distributer secured toit, so as to be made movable therewith, as described in my applicationfiled August 28, 1886, Serial No. 212,040, if desired.

In Figs. 7,8, and 9 I have illustrated the invention as applied tofeeding and driving nails of comparatively large size forattachingnails, and nails of very small size for wearingnails and forornamentation. \Vhen these two gangs of nails of different sizes areused, the attaching-nails are generally driven first as in blind-nailingand a top lift then attached,and the small nails then driven through thetop lift, although'I would say that both gangs may be driven as forflush-nailing, and when two full gangs are used, the first forblind-nailing and the second for flush-nailing, I prefer to use arevolving head having five or six arms, substantially as shown in Fig.14:, the first of which supports a gang or group of awls, a, for formingthe holes'for the attaching of large nails, the second of which supportsa gang or group of drivers, a, for driving the attaching-nails,the thirdof which supports a top-lift spanker or top ,-lift-attaching device, thefourth of which supports agang or group of shorter and smaller awls forforming the smaller line of holes, the fifth of which supports thesmaller drivers, a, for driving the small nails, and the sixth of whichsupports a compound spanker and breaster.

To permit nails of different sizes to be used,

as above specified, it is necessary that the templet should have'theline of large holes m and theline of small holesm set much more closelythan the line of large holes m. The nail carrier must have the line oflarge holes m and the line of small holes m set much more closely thanthe line of large holes m The supplemental nail-carrier must have theline of large holes 111 for delivering nails to the large holes at ofthe nail-carrier, and the line of small holes m set more closelytogether for delivering nails to the small holes m of the nail-carrier.

When nails of two sizes are then used, the compound distributer G G willbe adapted to receive nails of two sizes, from two nail-making. devicesone for making large nails and delivering them through the distributerG, and the other for making small nails and distributing them throughthe passage of the distributer G.

I would say that the time of operation or movement of the supplementalcarrier-plate E may be such as to deliver both gangs or groups of nailsto the carrier 0 at successive operations, and before the carrier ismoved to deliver them to the templet, so that the two groups should bedelivered to the nail-driving devices at the same time to be driventogether. When the machine is thus operated, it will be desirable to useblocks carrying a double gang of awls and a double gang of drivers, asrepresented in Fig. 11.

Having thus fully described my invention, I claim and desire to secureby Letters Patent'of the United States 1. The combination, in a gangnailing-ma chine, of the nail-driving devices, a templet, B, having twosets of holes, a nail-carrier, 0. having two sets of holes, and asupplemental nail-carrier, E, having two nail-holders movable across thesaid nail-carrier, and adapted to deliver in successive order nails tothe two lines or groups of holes in said carrier, substantially asdescribed.
